The factory operates for 11 hours a day and the machine that makes the wheels can produce at most 80 wheels per day.

c = number of cars produced and t = number of trucks produced

What are some constraints on the manufacture of the trucks and cars

The constraints I have so far are:

1. c >= 0

2. t >= 0

3. c4 +t6 <=80

I'm unsure about the 3rd constraint, can someone help me out and let me know the 4th constraint and if the 3rd constraint is correct?

I feel like I have confused myself!
